The Cirrus Airframe Parachute System (CAPS) is an interesting concept. If your plane gets into trouble, just pull the rip-cord and a parachute comes out and lowers the plane safely to the ground. Well last weekend over the picturesque Blue Mountains of NSW a Cirrus aircraft equiped with CAPS got into difficulties (the engine stopped!) and the pilot hit the button and the plane and his three passengers were lowered to the ground. All concerned walked away.
If the results were not so serious, I would speculate that it almost looks like an advertisement for the product. Now if they could just build a parachute big enough for an Airbus A380.
